CAP-RETAINER FOR DEFORMABLE TUBES.

Specification of Letters Patent.

Patented Oct. it, 1916.

Application filed September 14, 1915. Serial No. 50,560.

To all whom it may concern:

Be it known that I, CHARLES CLARK, a citizen of the United States,residing in-the borough of Manhattan of the city 01"? New York, in thecounty of New York, 1n the State of New York, have invented certain newand useful Improvements in Cap-Retainers for Deformable Tubes, &c., ofwhich the following is a specification, reference being had to theaccompanying drawings, forming a part hereof.

Ina co-pending application filed by the present applicant on August 271915, Serial No. 47,586, there is shown and described a retainer for thecaps of collapsible tubes or the like comprising, broadly, two linksloosely interconnected, one of which is atfixed to the cap and the otherof which 1s loosely engaged with the threads of the neck of the tube.

The present invention relates to retalners of the same general characterbut seeks to provide retainers which may be more satlsfactory under someconditions of use.

The objects of the invention are essentially those stated in theco-pending case but, in addition, the present application seeks to covera retainer composed, broadly, of two links loosely interconnected, oneof which is aflixed to the container and the other of which is looselyengaged with the cap whereby the cap may rotate freely with theco-pending case may be embodied in many different forms although for thepurposes of this application it has been deemed suflicient to illustrateonly two such forms.

In the drawings Figure 1 is a view in side elevation of a fragment of acontainer on which is threaded a cap of usual construction and to whichis applied the improved retainer. Fig. 2 is a view showing the cap andcontainer illustrated in Fig. 1 but with the cap removed and theretaining links illustrated in section. Fig. 3 shows a modifiedconstruction of retainer. Fig. 4. is :1 detaiview of the link about theneck of the container shown in-Figs. 1-3. Fig. '5 is a detail view ofthe link about the cap shown in Fig. 3 prior to the upsetting of thelugs thereon. Fig. 6 is a detail view of the retaining ring shown on thecap in Fig. 3.

In the drawings, the usual collapsible container a is formed with athreaded neck a on which may be secured a cap I) to close These deviceslike those threaded closures of this kind by providing I a suitableretainer by means of which the cap is always connected to the tube.improved retaining device comprises a suitable link a secured fixedly tothe container 64 and a second link cl loosely connected with the firstlink and with the cap 1) whereby free rotativemovement of the cap on thethreaded neck is permitted, asduring removal and replacement.

The precise means by which one of the links 0 is engaged permanentlywith the container a or with the threaded neck a thereof, and by whichthe other link d is so connected with the cap I) as to permit freerotative movement thereof, may take widely to the diameter of the screwthreads of the 90 neck a so that the link 0 may be threaded to the baseof the threads on the neck and then have pressure applied to the barbsfor the purpose of embedding them permanently in the soft metal of theneck. The other'link d may be formed from a piece of wire which ispassed around the cap 6. and disposed loosely within a circumferentialgroove 6 formed thereon, this wire, of course, being of suflicientstiffness to retain its form and to resist any'ordinary strains imposedthereon and which tend to withdraw it from the groove 12. This wire hasformed at its free end an eye 03 which is passed through the eye 0 ofthe other link 0, thereby forming a loose connectionbetween the twolinks and permitting the cap I) when removed from the neck a to swingback from the mouth of the neck to a position away from the contents 'tobe discharged. In this connection, it is to be noted that the links aand d are both of sufiicient length to permit the cap 6 to be held wellawayfrom the mouth of the neck.

The wire d being disposed loosely Within the ,4 groove b permits freerotati've movement of the cap I) along the threaded neck a for purlinkon the threaded neck rotated with respect thereto,

In the 'modlfiedconstruction suggested in Fig. 3 a link similar in allrespects to that described hereinbefore may be .aflixed to the neck ofthe tube a while the other link D on the cap is held thereon in aslightly different way. In this construction, it is unnecessary toprovide the cap B with a circumferential groove. The link D as shown inFig 5 is stamped from sheet metal and formed with a ring which hasaninner diameterslightly greater than the outer diameter'of the cap sothat the link may be slipped loosely on to thecap. This link has lugs orears D stamped'mteg'ral therewith about the outer 'periphery-ofjthe ringportion. After the link D has been placed loosely in position on the capa plain ring 0 is forced on to the capwith a driving fit so that it isheld by the cap and rotates therewith. The ears D on the linkiD are thenbent over to engage theguard ring 6 loosely so that while the link-Dcannot be removed from the cap 18 it permits relative rotation of thecap w th respect to it, as during the removal or replacement of the cap.The link D has an eye D which engages the eye 0 of the other link 0 asexplained hereinbefore.

-Modifications within the scope of, the

claims hereunto appended may be made without departing from the spiritof this invention, the general purview whereof has been indicated inthis specification and while reference is made to the ailixing of thelink 0 to the container it is evident that the link may rotate withrespect thereto.

What I claim is 1. In combination with a vessel having a threaded neckanda threaded cap therefor, a retainer for the cap comprising a bandencircling the cap loosely, whereby the cap may rotate with respect tothe band and another band encircling the neck of the vessel and disposedWithin the threads, and means carried by said last named band to engagethe metal of the neck fixedly to hold the band against rotation, andsaid bands being pivotally engaged with one another.

2. A retainer for the threaded cap of a vessel, comprising aringencircling the cap loosely and having lugs formed thereon and an eye,asecond ring aflixed to the cap with a driving fit and engaged looselyby the lugs on the first ring, and aband encircling the neck of thevessel fixedly and having an eye engaged loosely with the eye of thefirst named ring. a
